Choosing the correct flange size is essential for comfort, security, and a leak-proof seal between the pouch and skin barrier. The best flange size is the one that matches your ostomy barrier and stoma size, ensuring a secure fit and minimizing the risk of leakage or skin irritation. SUR-FIT Natura Closed Pouches come in flange sizes such as 2-3/4" (70 mm) and 1-3/4" (45 mm), covering a range of needs for different stoma and barrier sizes. For example, the Convatec 421893 Natura+ Standard Pouch is designed for a 2-3/4" flange, while the Convatec 401909 SUR-FIT Natura Flange Cap fits a 1-3/4" flange. Having multiple flange size options ensures you can select the product that best fits your unique requirements.
